Re: Banner messages - avoiding on "ssh host cmd"

but if there is a way to access the machine sans warning, then the whole legal purpose is thwarted, unfortunately.

If using a Bourne shell variant (bash, ksh, zsh, sh, etc) then just discard stderr:

   ssh hostGottaWarn command 2>/dev/null

Of course if you need stderr of the command, you're going to need to try something else, like

Do you need help?X

   ssh hostGottaWarn command 2>&1 | egrep -v "(strings|that|match|banner)"

which of course redirects stderr to stdout, causing an entirely different problem.

If you're using csh or tcsh or then I don't remember how or if you can redirect stderr. Instead, get a real shell - csh variants should be burned to the ground.
